Need suggestions on why for 1 particular external email, the banner was not highlighted to draw attention.
The verbiage message is there but not highlighted as it should be.
Hi @nbraz1980,
It will be really difficult to ansewer your question without more detailed information, but let me suggest some steps about where to check:
- Check if the sender email address and/or domain is in your Outlook safe senders list.
- Check the transport rule configuration and exceptions.
- If you also enabled "ExternalinOutlook" feature in PS, run this cmdlt and check if the sender domain is in the Allowlist:
Get-ExternalInOutlook | fl
- Please also check in OWA in order to know if it may was a simple client issue.
- Analyze the message header will also be helpful:
Message Header Analyzer (mha.azurewebsites.net)
Hope this helps. :)
